PEGGING AND SEWING JACK.

SPECIFICATION forming part of Letters Patent No. 440,483, dated November1 1, 1890.

Application tiled April 19, 1890.

To all whom zit may concern:

Be it known that I, ROBERT T. LEMMoN, J r., of Mount Airy, in the countyof Pittsylvania and State of Virginia, have invented certain new anduseful Improvements in Pegging and Sewing Jacks; and I do hereby declarethe following to be a full, clear, and exact d escription of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form part of this specication.

My invention relates to an improvement in pegging and sewing jacks 3 andit consists in the construction and arrangement of parts, which will befully described hereinafter.

The objects ot my invention are to form the spring-actuated lever in asingle piece and hold it in any desired position by means ot a ratchet,and thus enable the last to be quickly adjusted and released, and toprovide a support which will allow the frame to be usedin either avertical or horizontal position, and thus adapt it to hold the last inposition either for pegging or sewing at the will ot the operator.

Figure 1 is a side elevation of a device which embodies my inventioncomplete. Fig. 2 is an edge view, the 'frame being shown in one positionin solid lines and in another position in dotted lines. Fig. 3 is avertical section taken through the upper end ot' the verticalsupport,showing the two sockets made therein.

A represents a suitable socket, which has a locking spring-actuated pinB attached toits upper end, and into this socket extends thevertically-adj ustable support C, upon the top of which the frame H isplaced. Extending vertically down into the top of the support is asuitable opening or socket I, and extending horizontally through the topot the support is a second socket G. Extending from the lower edge ofthe L-shaped frame H is a projection or tenon J, which extends intoeither the vertical or horizontal socket or opening, according to theposition in which it is desired to use the frame. A fastening A isplaced at the junction or intersection ot the said vertical andhorizontal sockets, so that it will secure the tenon J in either thevertical or horizontal socket. It the frame is to be used in a verticalposition, it is placed upon Serial No. 348,743. (No model.)

the top of the support, but it the frame is to be placed in a horizontalposition so as to enable the last to be turned upon its side for thepurpose of enabling the shoe-maker to sew the bottom to the upper, thenthe tenon or projection on the frame is passed into the horizontalsocket or opening, and the i'rame is then held in a horizontal position.Springactuated locking-pins are used to lock the frame rigidly to thesupport, but any other form of device may be used for this purpose. Bymeans of the spring locking-pins here shown the parts can be quicklyfastened or loosened at the will ot the operator, and thus enablechanges to be made from one position to another with but very littleloss of time.

Pivoted in the upper end ot the L-shaped frame II is the L-shaped leverO, which has its upper end so shaped as to extend into, support, andlock the last in position in the usual manner. The lower and longer endot this lever O extends through a vertical opening in the support N, andupon the outer edge ot this support is formed a ratchet Q, with whichthe end of the lever engages for the purpose of locking the last inposition. The lever is so shaped as to engage with this ratchet as it isforced downward against the spring R, which bears against the under sideot thelever and returns it to position whenever it is left free to move.The outer tree end ot' the lever, by passing directly through thesupport, enables the lever to be made in a single piece and in thecheapest, simplest, and most durable form, at the same time that itenables the last to be more quickly locked in position and released thancan be done where the parts are constructed in the usual man ner. Thesupport for the toe of the last is made adjustable back and forth uponthe frame H by means of a spring-actuated locking-pin of any suitableconstruction. This support acts as a guide for the vertical movement otthe free end of the lever II and prevents the lever from having anylateral movement or from becoming displaced at any time.

In order to prevent the last from becoming injured by having its edgesfrom coming in contact with the upper end of the frame H, there isplaced upon or secured rigidly to the lever above the top of the trame aplate T, which is so shaped upon its upper surface as IOO IVO

to conform to the shape of the top edge of the last. This plate forminga wide and long bearing for the last just at that point where the vmostwear occurs, the last is notbroken, split, or otherwise injured, as isalways the case where no provision is made for protecting it at thispoint.

As will be seen, by making the lever in a single piece the straps, thescrews, and the other fastening devices which have heretofore beenemployed are entirely done away with and the cost of the jack is verygreatly reduced and its construction lightened and simplified. By makingthe frame removable from the support and enabling it to be used in botha horizontal and a vertical position theshoe that is being made can beturned into vthe most convenient position for the shoet maker,r therebyenabling him to work easily and rapidly.

While I here show the support vhaving a lvertical and al horizontalsocket in its end and the last-supporting frame having a projection,

it Will be readily understood that this arrangement can be reversedthatis. the sup- 'port provided with a vertical and a horizontal projectionand the last-supporting frame with a socket to receive the saidprojections- Without departing from the spirit of my invention.

yHaving thus described my invention, I

1. The combination ofthe L-shaped frame proj ecting ends pivotedtogether, and a vertical toe-support longitudinally and adj ustablysecured at its lower end to the long end of the L-shaped frame, and avertical rack-bar se-4 I -shapedframe having its longitudinal portionprovided with apertures, an I i-'shaped lever having its verticalportion pivoted to the vertical portion of the saidframe and extendingparallel therewith, I and a" toe-rest which has its lower end engage thehorizontal portion of the frame and having a piniwhich extends into th'esaid apertures of the frame, whereby it is longitudinally adjustablethereon, substantially as specified.

In testimony whereof I afiix m yvsignatu re in the presence of twowitnesses.
